Rotary Mower Gearbox – Replacement of Comer Code LF-139A
The rotary mower gearbox LF-139A is a component of a rotary mower that helps transfer power from the mower’s engine to its blades. The gearbox typically contains gears and bearings that help to reduce the speed of the mower’s engine while increasing the torque applied to the blades. This allows the mower to cut through grass and other vegetation effectively.

The Comer LF-139A Rotary Mower Gearbox is a component of a rotary mower that helps transfer power from the mower’s engine to its blades. The gearbox typically contains gears and bearings that help to reduce the speed of the mower’s engine while increasing the torque applied to the blades. This allows the mower to cut through grass and other vegetation effectively.
The gearbox may also have additional features. Such as a clutch, engaged or disengaged to start or stop the blades, and a gear reduction system, which allows the mower to operate at different speeds to accommodate different types of terrain or grass thicknesses.
It’s important to maintain and periodically inspect the gearbox to ensure that it’s operating smoothly and efficiently. Regular maintenance may involve lubrication of the gears and bearings, an inspection of the seals and bearings for damage or wear, and replacement of any damaged or worn parts.

The Rotary Mowers Gearboxes Inspection and Maintenance
1. for the mower gearbox with oil level plugs.
Check the oil level and whether it is qualified; install the oil level plug.
2. the replacement of oil.
Oil’s The reducer should be made at the operating temperature. Cut off the power to prevent electric shock! Wait for the reducer to cool down without any danger of combustion. After cooling, the oil’s viscosity increases, making it difficult to drain the oil.
3. the oil-level inspection.
Cut off the power to prevent electric shock! Wait for the lawn mower gearbox to cool; remove the oil level plug to check if the oil is full; install the oil level plug.
4. the oil inspection.
Cut off the power to prevent electric shock! Wait for the lawn mower gearbox to cool; open the oil drain plug and take the oil sample; check the viscosity index of the oil; if the oil is turbid, it is recommended to replace it as soon as possible.
PTO Shafts and Rotary Mower Gearboxes
When choosing a PTO shaft for a rotary mower gearbox. It is necessary to ensure that the shaft is the correct length and diameter for your specific application. The shaft length should be measured from the center of the PTO spline on the tractor to the center of the input spline on the gearbox. The diameter of the shaft will depend on the horsepower of the tractor and the size of the gearbox.
It is also important to choose a PTO drive shaft that is rating for the correct horsepower and torque requirements of your rotary mower gearbox. This information can typically be found in the manufacturer’s specifications for the gearbox.
In addition to selecting the correct PTO shaft. It is important to inspect and maintain it regularly to ensure safe and efficient operation. In addition to the LF 139A type, a wide range of other rotary mower gearboxes and PTO shafts are available.
